deep foot cracks to me,my child,and to my father

Hi Anonymous,
Thank you for your question and for finding EmpowHER. It sounds like you and your family need to be seen by a doctor about this. The bad smell could indicate an infection is present. It is not uncommon in Winter weather for skin to get very dry and cracked, and if an infection such as staph or strep can get in there, it can cause a lot of trouble for the person dealing with it. If your foot or leg swells and begins to seep liquid, you need to get immediately to a hospital.
We unfortunately aren't doctors and cannot diagnose you, so you really should see a medical professional about this skin condition you describe so you and your father and child can be properly treated.
Good luck, and let us know what you find out.
